New findings on the effectiveness of powders against bedbugs: Terre de Sommières and diatomaceous earth in the spotlight

28 August 2024

A recent study by entomologist Jean-Michel Béranger has revealed interesting new data on the effectiveness of powders in the fight against bed bugs. The research compares several types of powder, including terre de Sommières, diatomaceous earth, and other substances such asgreen clay or talcum powder.

The results show that Terre de Sommières can be just as effective as the tried-and-tested professional Terre de Diatomée, with bedbug mortality rates ranging from 75% to 100% for prolonged exposure. However, it is essential to remember that these solutions should always be used in conjunction with traditional chemical and mechanical bedbug control methods, such as washing infested textiles at 60 degrees, freezing at -20 degrees, and thoroughly vacuuming the affected rooms.

Diatomaceous earth: Effective, but with care

Although terre de Sommières has proven its effectiveness, it’s important to point out that diatomaceous earth, a more widely used product, also remains a formidable weapon against bed bugs. However, a few precautions must be taken. When used in powder form, diatomaceous earth can be harmful to the lungs if inhaled. This makes it a delicate product to handle, especially in confined or poorly ventilated spaces. Also, some commercially available diatomaceous earths can prove ineffective, and it’s imperative to select professional diatomaceous earths.

Terre de Sommières studied by entomologist Jean-Michel Béranger

At Sereni-d, we have developed a practical and safe professional solution: a diatomaceous earth-based aerosol. This formulation considerably reduces the risks associated with powder inhalation. Thanks to the aerosol, diatomaceous earth adheres directly to treated surfaces without remaining airborne, making application safe and effective. Its precision nozzle enables narrow, localized applications, reaching all bedbug hiding places.

How to use these products

To maximize the effectiveness of powders, here are a few simple tips. For example, after cleaning your infested bedding and furniture, you can sprinkle terre de Sommières or apply diatomaceous earth spray to sensitive areas such as box springs, mattresses and even bed frames. This approach, which should be combined with other mechanical and chemical control measures, increases your chances of complete eradication.

In short, while the study shows that terre de Sommières is a promising solution, the effectiveness of diatomaceous earth, particularly in aerosol form, should not be overlooked. Prevention and a variety of methods remain the best strategies for getting rid of bed bugs for good. Discover the full Sereni-d range for a complete bedbug treatment.
